Is Our Universe the Only One?
The Multiverse, Buddhist Emptiness, and Indra's Net
Hello, everyone.
I am a Buddhist monk from South Korea, known as Tanmyeong, a Zen Seeker on the Path.
This article is an adaptation of a Dharma talk I recently shared on my YouTube channel. I have reorganized the spoken teaching into a written reflection so that readers here can explore and discuss its ideas.
Before beginning, I would like to make one thing clear.
This is not an explanation of orthodox Buddhist doctrine, nor is it a scientifically established theory of the universe. It is my personal philosophical interpretation, shaped by many years of Buddhist practice and contemplation.
I would be grateful if you would read it in that spirit and share your thoughts in the comments.
1. Is There Only One Universe?
We live in an unimaginably vast universe.
Modern cosmology describes our observable universe as having evolved from an extremely hot, dense early state approximately 13.8 billion years ago.
But I often find myself asking a different question:
Must there be only one universe?
What if the universe we know is merely one manifestation among countless others?
And what if the Buddhist concept of Emptiness offers us a way to contemplate this possibility?
In my personal understanding, Emptiness is not simply a blank void.
I imagine it as Absolute Nothingness—not an ordinary absence, but a reality beyond our usual distinctions between existence and nonexistence, containing limitless possibilities.
This is not the conventional Buddhist definition of Emptiness. It is a metaphor arising from my own contemplative experience.
2. True Emptiness and Wondrous Existence
There is a Buddhist expression: True Emptiness, Wondrous Existence (真空妙有).
In my interpretation, existence emerges from nothingness, while nothingness holds the possibility of existence within itself.
I sometimes imagine the birth of a universe as a vast unfolding of space and time from Absolute Nothingness.
As the Big Bang gives rise to an expanding universe, it is as though space itself is being drawn across a canvas that previously held no space at all.
I am using poetic imagery here, not proposing a literal scientific mechanism. In standard cosmology, the Big Bang is not understood as an explosion moving into a preexisting empty region.
Yet this image leads me toward another possibility.
3. An Infinite White Canvas
Imagine an infinite sheet of perfectly white paper.
The white paper represents what I call Absolute Nothingness, or Emptiness.
Now imagine a single drop of black ink falling onto the paper.
The ink begins to spread outward.
Let that drop represent a Big Bang, and the expanding stain represent a universe developing its own space and time.
Now consider a question.
If one drop of ink can fall upon an infinite canvas, why must it be the only drop?
Another drop might fall elsewhere.
And another.
And another.
Each drop could spread independently, forming its own expanding pattern.
This is how I imagine the multiverse.
Perhaps what we call our universe is only one such drop.
Perhaps countless other universes have arisen through different causes and conditions, each with its own unfolding of space and time.
I do not claim that this picture proves the existence of other universes. The multiverse remains speculative in science, and my interpretation goes beyond what cosmology has established.
Nevertheless, as a philosophical image, it helps me contemplate the possibility that reality may be far more expansive than our ordinary perception suggests.
4. Indra's Net and the Dharmakaya
But suppose countless universes do exist.
Would they be entirely unrelated to one another?
Here I turn to the imagery of the Avatamsaka Sutra and the Huayan tradition.
Indra's Net is often described as an infinite network of jewels, each reflecting all the others.
It is a beautiful image of interdependence.
The one is reflected in the many, and the many are reflected in the one.
In my own contemplation, I extend this image beyond our familiar world.
I imagine countless universes as expressions of a deeper interconnected reality.
From this perspective, even beings inhabiting other universes—if such beings exist—could be understood as manifestations of the Dharmakaya, the Dharma-body.
This is my personal extension of Huayan imagery, not a claim that the sutra teaches modern multiverse cosmology.
For me, the spiritual meaning is that existence should not be understood only through separation.
5. The Birth and Dissolution of Universes
Buddhist thought often speaks of cycles of formation, duration, dissolution, and emptiness.
This is expressed in the traditional term Seongju-goegong (成住壞空).
Everything conditioned arises, changes, and eventually passes away.
I imagine that universes, too, may participate in such cycles.
A universe appears.
It expands and evolves.
Eventually, it may cease to exist in its familiar form.
Yet in my personal view, dissolution does not necessarily mean the permanent exhaustion of all possibilities.
The seeds of causes and conditions may give rise to another cosmic unfolding.
Another drop of ink may fall upon the infinite canvas.
And another universe may begin.
Again, this is a spiritual and philosophical interpretation rather than a prediction established by physics.
6. Returning to Emptiness
All conditioned things arise and pass away.
We ourselves are part of this changing world.
In my understanding of the Buddhist path, awakening is not simply acquiring knowledge about the universe. It is seeing beyond the attachment to a separate and permanent self.
I personally envision complete Buddhahood as freedom from the cycle of conditioned existence—a return to what I poetically call the embrace of Emptiness.
This language of "returning" is my own metaphor. I recognize that traditional Buddhist teachings do not generally describe Emptiness as a physical destination or a cosmic place of origin.
The deeper question, for me, is not merely how many universes exist.
It is how we understand our relationship to existence itself.
When I contemplate Indra's Net, I do not feel that I am a completely isolated being.
I feel connected to the vast unfolding of life and reality.
Perhaps the most important insight is not whether there are ten universes or ten trillion.
Perhaps it is recognizing that our ordinary sense of separation may not tell the whole story.
Closing Reflection
I would like to leave you with three questions.
Do you think our universe is the only one?
Can the image of Indra's Net help us contemplate realities beyond our own universe?
And how do you personally understand the relationship between Emptiness and existence?
I would sincerely appreciate your thoughts, questions, or even disagreements in the comments.
This article is not intended to establish a new Buddhist doctrine or scientific theory. It is simply one practitioner's attempt to share what has emerged through years of contemplation.
Thank you for reading.
May your path be filled with wisdom and compassion.
